Beetle Visitation to Healthy ʻŌhiʻa Trees Experiment 1

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-07-26T00:00:00Z
These data contain the documentation of ambrosia beetle (Coleoptera: Curculionidae) attack or colonization on healthy ʻōhiʻa trees that were wounded or un-wounded. Beetles are attracted to stressed trees that emit an ethanol scent which was simulated with wounding. Beetles were collected on sticky cards and gallery (tunnels where beetles live) formation was documented.
